More on wiki

I thought "this is so easy!" and scarily so. Truly anyone could do this. If all students performed this exercise they would really wonder about the source's reliability. But, what I use Wikipedia for is pretty verifiable-- in other words, I look for book titles, or other names of related people that i could explore some other way. also, I am curious about who spends a lot of time writing articles and doing scholarship for this forum. Are they shut ins? Elderly, retired, out of work? It is a certain expression of altruism to make free public knowledge but who has the time?
